| | Description | |
| Comments: | Herja jamesonite contains manganese. Not enough Mn (<1 wt.%) to make Benevidesite (>1 wt.%), but enough to affect the diffraction pattern. Marc Wilson at the Carnegie in Pittsburgh found the grey needles enclosed in calcite to be jamesonite. | | Habit: | fine felted needles | | Colour: | grey | | UV Fluorescence: | none | | Quality of samples: | Good crystals or rich for species - important (!) | | Confirmation | |
| Validity: | Believed Valid | | References | |
